In preparation for qemu maybe actually supporting variable refcount widths in the far future, drop the hardcoded REFCOUNT_SHIFT and instead use the value as given by the image.
Also, the qcow2 documentation gave the width of a refcount block entry as sizeof(uint16_t), which is wrong for any refcount order other than 4. Fix that. This is a follow-up to my "[PATCH v5 00/11] qcow2: Fix image repairing" series and therefore depends on it.
